GEORGE 1?. YOUMANS, OF GALESBURG, MICHIGAN, ASSIGNOR T KALAMAZOO TANKAND SIIJO (70., OF KALAIVIAZOO, IVIICHIGAN.

SILO.

Application filed October 16, 1913.

To all whom it may concern:

Be it known that I, GEORGE P. YoUMANs, a citizen of the United States,residing at Galesburg, Michigan, have invented certain new and usefulImprovements in Silos, of which the following is a specification.

This invention relates to improvements in silos. The main objects ofthis invention are: First, to provide an improved block wall silo.Second, to provide in a silo, an improved structure having a continuousdoor opening. Third, to provide in a silo, an improved wall reinforcingmeans. Fourth, to provide an improved silo which is attractive inappearance and at the same time comparatively economical to produce.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification, in which:

Figure I is a detail front elevation of a structure embodying thefeatures of my in vention. Fig. TI is a detail horizontal section on aline corresponding to line 22 of Fig. I. Fig. III is a detail horizontalsec tion on a line corresponding to line 33 of Fig. I. Fig. IV is adetail vertical section on a line corresponding to line 4 4 of Fig. II.Fig. V is adetail vertical section through the doors, on a linecorresponding to line 55 of Fig. I. Fig. VT is a plan view showing thejoints of the sections of the reinforcing hooks 10.

In the drawing similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the structure illustrated is a circular silohaving a con tinuous door opening. The wall of the silo is formed ofblocks 1 laid in cement or mortar 2. These blocks are preferably cementblocks or vitrified blocks or bricks.

At each side of the door opening are special blocks 3 which I designateas door casing blocks. These blocks 3 arehollow and Specification ofLetters Patent.

open at top and bottom so that when laid they form a continuous channeladapted to receive a filler 4 of concrete, the filler constltutingcontinuous columns at each side of the door opening. This fillerreinforces the casing blocks and assists the mortar or cement in whichthey are laid, in keeping them in place in the wall. These blocks areshouldered at their inner ends, as at 5, their inner corners beingpreferably rounded to the shoulders, as at 6.

The angle iron casing uprights 7 are arranged wlth their angles over thefront angles of the shoulders. See Fig. H. These uprights 7 are held inposition by the angle iron cross bars 8. The cross bars are preferablyprovided with struck-in lugs 9 which engage the uprights, as shown inFig. TI, and may be riveted or otherwise secured to the front arms ofthe uprights, the securing means not being shown.

The wall is provided with reinforcing or tie members or hoops 10 whichare laid with their ends projecting into the hollow blocks and securedto the vertical tie rods 11 arranged therein. The filling at for thecasing blocks embeds these tie rods and the projecting ends of the hoopsor reinforcing members 10 so that they are supported in position. Thetie rods constitute reinforcing members for the columns of filling material. These hoops 10 are formed of band iron and laid flat between thetiers of bricks or blocks. This permits a thin cement oint. The hoopsare given a quarter twist at 21 so that they may be conveniently lappedaround the tie rods 11. F or convenience in handling the hoops arepreferably formed in sections having corrugated oint portions 12, thejoint portions being lapped so that their corrugations engage when laidin the wall. These corrugations are clamped together, being, in fact,embedded with the weight of the wall thereon so that an effective jointis provided. At intervals I provide continuous hoops 13 which extendacross the door opening, the hoops 13 being preferably arranged over thecross bars 8.

The doors 15 are arranged to be superimposed one upon another and toclose against the inner sides of the casing blocks 3 which are providedwith flattened portions adjacent to their inner ends which constitutedoor seats 16. See Fig. 11. The door hinges are preferably thosedescribed in my application for Letters Patent filed October 28, 1912,Ser. No. 728,186.

The hinge members 17 are provided with pintles 18 on one of the casinguprights 5. The hinge members 17 are curved rearwardly at 19 to clearthe casing when the doors are swung in. The clamping members 20 engagethe opposite upright when the doors are closed and coact with the hingemembers 17 in clamping the doors in place.

As the details of the hinges are fully described in my application forLetters Patent referred to and as they constitute no part of my presentinvention, 1 do not describe the same with further detail herein.

With the parts thus arranged, I secure a block wall silo having acontinuous door opening, which is not likely to crack or bulge orotherwise get out of shape. The structure is very attractive inappearance and is at the same time quite economical to produce and isvery durable.

have illustrated and described my improvements in a desirableembodiment. I have not attempted to illustrate or describe certainmodifications or changes in structural details which I contemplate, as Ibelieve the disclosure made will enable those skilled in the art towhich my invention relates to embody or adapt the same as conditions ortaste may dictate. I desire, however, to be understood as claiming myimprovements specifically in the form illustrated as well as broadlywithin the scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
